Title: Improvements in the dry separation of minerals, particularly applicable to the dry cleaning of coal
IPC: B03B4/02
Filed: 1944-11-16
Abstract: 584,555. Separating solid materials. SAXON ENGINEERING CO., Ltd. (formerly BERRISFORD. Ltd., W. H.), and SHAWCROSS, G. E. Nov. 16, 1944, No. 22735. [Class 117] In apparatus for the dry separation of minerals such as coal having' a sloping perforated table 1 which is oscillated obliquely in a direction to feed the material up the slope and is supplied with air from the under side, the direction of oscillation of the table is not the same at both ends, that at the lower end having a larger vertical component. Discharge weirs 31 and 38 are fitted at both ends, and the table surface is made rough or uneven to ensure the transmission of the conveying effect to the material in contact with it. The last effect may be obtained by serrating the table surface with steep fronts facing the upper end and gentle reverse slopes. Alternatively the table surface may be formed of wire mesh. An air supply duct with a flexible portion 26 is attached to the bottom of the table and contains control dampers 28. Weir 38 is sloped to permit easy sliding of the heavier material over the end. The table is mounted to oscillate on links 14 and 15, the latter making a smaller angle with the horizontal than the former in order to produce the desired difference in the vertical component of the oscillation at each end. Oscillation is effected by an eccentric 18 which may be adjusted to vary the slope of the table. The material is fed into a chamber 47 where dust is removed by an air blast and the vibration due to the table oscillation feeds the material therethrough to the table itself.

Title: Improvements in the process of manufacturing smokeless fuel briquettes
IPC: C10B53/08
Filed: 1936-08-19
Abstract: 483,549. Materials for making coke. KERN L. Aug. 19, 1936, No. 22854. [Class 55 (ii)] In the preparation of carbonized fuel briquettes, material such as bituminous, lignitic, or anthracite coal, slack, waste or shale is treated with an electropositive solution such as hydrochloric acid or an acidic chloride to bring ash-forming constituents into colloidal form. The mixture is pressed with a colloid precipitating electro-negative solution such as sodium hydroxide, and moulded, the product being heated in the absence of air and coked. In an example bituminous coal is ground and then masticated with dilute hydrochloric acid. Some dilute manganese chloride is added followed by a solution of sodium hydroxide which precipitates the metals and silica as colloidal gels while the mixture is thoroughlyagitated. The plastic mass is briquetted and dried at about 125‹ C. and then coked in vertical ovens at 700‹ C. Chlorides recovered with the distillate gases may be utilized as solvent instead of hydrochloric acid. If the coal contains a large amount of sulphur acidified manganese chloride including a large proportion of iron is used as colloid forming material, the oxides of manganese and iron subsequently precipitated forming stable compounds with the non-volatile sulphur on coking or combustion. U.S.A. Specifications 1,899,808 and 1,899,809 are referred to.
Patent GB-460456-A (GB)
Title: Improvements in stop mechanism for machines for winding yarns or threads, filaments or analogous materials
IPC: B65H63/036
Filed: 1935-08-16
Abstract: 460,456. Stop-mechanism for winding- machines. HOLT, H. Aug. 16, 1935, No. 23030. [Class 120 (ii)] In a machine for winding yarns or threads on paper tubes, cones, or other bodies driven from rolls or drums and in which levers or frames are provided normally to hold the driven device in contact with the driving drum, and to permit separation of the driving or driven parts on stoppage of the machine due to breakage or termination of the yarn or thread, revolution of the spindle is instantly and positively stopped by means, operative as it is moved away from the driving roll, to cause engagement of a latch with a catch wheel on or in driving connection with the spindle, the latch being subsequently disengaged. The spindle c mounted in cradle b and carrying a paper tube on a wooden block is driven from the drum a. The cradle b is mounted on an axle d in a frame e oscillatable on axis f in the frame g of the machine. The prop h holds frame e in position and is movable by detector mechanism on breakage or termination of the yarn to permit frame e to move to the inoperative position shown in Fig. 3. The spindle c has a catch wheel i with radial faces i<1> for engaging a hook j<2> on latch j, a slot j<1> in which surrounds a peg k on one arm of the cradle b A spring l ordinarily holds latch against a'stop m. A surface j<3> bears against stop m when the latch j is moved lengthwise by engaging catch i so as for a time to hold the latch and catch in engagement. A shoulder j<4> prevents successive movement of latch j. A rod n formed at its upper end with a hollow n<2> and mounted on cradle b is slidable in a guide o and at its lower end has a slot n<1> embracing a pin p located in one end of axle d, and rests against a member r. The upper end of the rod rests against a spring s on guide o and the rod is spring-urged in one direction by a spring q secured at one end to stud p and at the other to rod n. On breakage or failure of the yarn, detector mechanism moves prop h, and frame e with cradle b and the body of yarn drops, causing the slidable rod n to be moved upwards by rest r against spring q and to tilt latch j into engagement with catch i which draws the latch forward until parts j<3>, j<4> engage stop m and stop the spindle. The reaction of the spindle to sudden stoppage permits the latch j to be raised after stoppage from the path of catch i by means of the spring l. The spring s permits the rod n to be moved back to operative position when winding is to be recommenced. If desired, the head of rod n or the member with which the rod engages could be made yieldable. The rod n instead of being spring-urged may have a follower element engaging in a cam slot. The Provisional Specification states also that a brake and brake wheel may be employed in place of the latch and catch arrangement.

Title: Improved apparatus for dehydrating mixtures of alcohol and liquid hydrocarbons
IPC: B01D3/00
Filed: 1923-09-14
Abstract: 204,697. Soc. Ricard, Allenet, et Cie. Sept. 30, 1922, [Convention date]. Motor spirit. - Mixtures of alcohol with gasolene, petroleum, benzene, &c. are dehydrated, and consequently stabilized for use as fuels', by a continuous process comprising passage through water - absorbing substances. The alcohol and the hydrocarbon are run from tanks A, B through a mixing funnel K, pipe T, and valves Q, S<1> to a tower D<1> containing potassium carbonate, sodium carbonate, calcium carbide, or other dehydrating agent, preferably mixed with inert material such as coke, asbestos, or granular pumice to prevent clogging. The treated mixture is then passed through the valves T<1>, S<2> for similar treatment in the series of towers D<2> - - D<n>. It is finally run through valves T<n>, R<n+1> and a pipe U to a storage tank. The solution of the potassium carbonate eventually formed by the water absorbed falls to the bottom of the towers, and is run off to a tank G through valves X<1> - - X<n> that are opened electrically when its level reaches that of the valves T<1>, T<n>, or as desired by the operator, sight-glasses r<1> -- r<n> being provided. Any gasolene separating in the tank G is forced by a pump M to the pipe T for retreatment; the solution of carbonate is withdrawn by a pump M<1> and heated to recover the absorbent for reuse. When the absorbent in the tower D<1> is exhausted this tower is cut out by closing valves Q, S<1>, T<1>, the tower D<2> is made the first by opening valves V<1>, S<2>, and a tower D<n+1> is introduced into and made the last of the series bv closing valves R<n+1> and opening valves S<n+1>, T<n+1>, R'. The tower D' is emptied of liquid through valve X<1> and the fuel absorbed by the pumice is vaporized by air or steam admitted through a valve P' and is passed through a pipe O<1>, trap C, water-valve E, and recovery tower F. The tower is then emptied through a door i<1>, recharged through a door t<1>, and reintroduced into the battery when the tower D<2> is cut out and tower D<3> is made the first of the series. A small quantity of ether, benzene, toluene, xylene, butylic alcohol, isoprophyl alcohol, or other liquid rendering the aqueous alcohol and the hydrocarbon fuel mixible with each other mav be added before passage through the towers. The gasolene may be washed with alkali solution before admixture with the alcohol in order to remove acid impurities. In an example, 80 litres of 0.728 gasolene and 20 litres of alcohol with or without 2 litres of ether are treated.

Title: Improvements in or relating to vacuum brake systems and apparatus for railway vehicles
IPC: B60T13/46
Filed: 1919-09-19
Abstract: 154,023. Louard, E. S., and Rawlings, V. P. Sept. 19, 1919. Fluid-pressure.-Railway vacuum brakes are provided, in addition to the usual fittings on a vehicle, with a valve operable from the sides of the vehicle to admit air below the brake piston, or connect the space above the piston to an additional vacuum reservoir, for obtaining two or more applications of the brakes after the vehicle has been detached from the train. In one form, a valve 14, Fig. 4, operated by a lever 24 puts a passage 12 connected to the upper part of the brake cylinder into communication with a passage 10, Figs. 3 and 4, connected to the additional vacuum reservoir to apply the brakes on a detached vehicle. The valve 14 is connected to a diaphragm 19 subject to atmospheric pressure on the outer side, and a ball check valve 34 allows air to be withdrawn from the vacuum reservoir to the train-pipe 2, but prevents passage of air from the train-pipe to the reservoir. The brakes can be released by the usual hand-valve, and successive applications made by means of the valve 14 until the vacuum in the reservoir falls too low. Fig. 7 shows a modified valve 48 operated by a lever 66 and cords 67, 68 to admit air, entering through ports 54, to the train-pipe 2 and so to the lower side of the brake cylinder to apply the brakes. The valve 48 is automatically locked in the open position by a catch 64 operated by a diaphragm 58 so as to engage bevelled surfaces on the valve stem as shown. The catch is automatically released after a predetermined time when the pressures on the diaphragm 58 equalize through a by-pass 59, the valve then being closed by a spring 55.

[Class 98 (ii)] Coloured emulsions or light-sensitive layers are produced by forming salts of lake-forming dyestuffs in the layer by double decomposition with salts of weak organic acids which do not desensitize or affect the stability of the emulsion. The salts may be chosen so as to provide a particular hydrogen ion concentration in the emulsion. The salts of acetic, propionic, butyric, capronic, acrylic, malic, maleic, adipic, aminic, or naphthalene sulphonic acids may be used. A layer containing dye may be bathed in a solution of the precipitant or a layer containing the precipitant in a solution of dye. In one example, a silver-bromide emulsion to which chrysophenine G has been added is treated with a solution of barium butyrate and formed into a layer in the usual manner. On this a second layer containing Antosine BN and barium butyrate or calcium acetate may be poured. Salts of organic bases such as guanidine adipate may be used. Specification 415,756 is referred to. The Specification as open to inspection under Sect. 91 includes the application of the process to filter layers. This subjectmatter does not appear in the Specification as accepted.
